SPECIFICATION forming part of Letters Patent No. 697,508, dated Api-'i1 15, 1902. Application tiled January 14, 1901. Serial No, 43,102. (No model.)

To all whom it may concern:

Be it known that I, FAY H. MARTIN, a citi- Zenof the United States, residing at Hydepark, in the county o f Norfolk, State of Massachusetts, have invented a certain new and useful Improvement in Loom Shuttles, of which the following is a specification, refer- 'ence being had therein to the accompanying drawings.

My invention consists in a loom shuttle having novel and improved threading arrangements enabling the yarn drawn from a cop or bobbin contained within the yarnchamber of the shuttle to be quicklyand conveniently led through the same in readiness for weaving, thel said arrangements being of a character to prevent the yarn from accidentally becoming unthreaded therefrom.

I have illustrated one embodiment of my invention in the accompanying drawings, in which latter- A Figure 1 shows in plan av loom-shuttle having the said embodiment of the invention applied thereto. Fig. 2 shows the same in side elevation. Fig. 3 is a view in vertical section on the plane indicated by the dotted line 3 3 in Fig. l lookingin the direction indicated by the arrows adjacentthe ends of such line. Fig. 4 is a View mainly in vertical section on the plane indicated by the dotted line 4 t in Fig. l looking in the direction indicated bythe arrowsadjacent the ends of such line. Figg is a view similar to Fig. 4, but showing the button and collar in vertical section. Fig. 6 is a side elevation of the button. Fig. 7 is also a side elevation of the button, viewing the same from the opposite side. Fig. 8 is a bottom View of the button. Fig. 9 is a plan view of the forward end of the shuttle with the button, collar, and securing-screw removed. Fig. 10 is a view in section on the line 10 10, Fig. l, showing the forward portion of the shuttle.

Having reference to the drawings, l designates the shuttle-body, and 2 the main or yarn receiving cavity or chamber thereof. 3 is a bobbin, with its yarn-load 4, mounted upon the shuttle-spindle 5 within the -said cavity or chamber 2.

6 is the delivery eye or educt in one side of the shuttle-body. 7 is a slit extending upward from the said delivery-eye to the top of the shuttle-body. Sis the threading-chamber into which the said delivery-eye and slit open transversely.

9 is a longitudinal groove or depression in the upper side of the shuttle-body, and 10 is a transverse wall of the shuttle-body, separating thethreading-chamber 8 from the yarn, receiving cavity or chamber 2. This wall is provided with an eye or passage 1l, Fig. 3, therethrough in line with the axis of the shuttle-spindle for the guidance of yarn from chamber or cavity 2 to the ,threading-chamber, the said eye or passage 1l being intersected at one side thereof bya nearly tangential slot-12, the walls of which at the top of the shuttle-body flare or diverge, as shown in Fig. 8, to facilitate the entrance of the yarn Ainto the same fromabove, the flare being in horizontal continuation of the longitudinal groove or depression 9, Fig. 1.

Within the threading-chamber are located a button 13 and` collar 14.. These two surround the stem of a screw 15, which is passed upwardly from below through a vertical hole' formed in the bottom of the said threadingchamber, the interior of the central hole of the button being threaded to it the thread of 'screw l5. Y By means of the said screw the button and collar are held in place. The upper end of screw 15 is formed with an axial hole 151, and after the parts have been assembled and properly adjusted into the desired working position the said upper end of the screw is expanded slightly, as by the use of a prick-punch, so as to cause the screw to bind in the central hole or eye of the button, thereby preventing accidental loss of adjustment or loosening and separation of theparts. The tightening effected in this manner is not to such an extent or degree as to preclude the possibility of separating the parts when it is necessary to do so. At its top the button is formed or provided with a horizontally-projecting liange 131, which is received within the counterbore 8l at the top of the threading-chamberv 8, the said flange overlapping the shoulder that is constituted by the bottom of the said counterbore, sufficient space being left between the flange and the said shoulder to permit of the free passage between them of the yarn in being drawn around under the said flange, and sufficient space being left between the body of the button and the wall of the threading-chamber to enable the said yarn to be carried down between them. The horizontal flange 131 at the top of the button being received within the counterbore at the top of the threading-chamber S, and thus located below the adjoining portions ofthe wood of the shuttle-body at the top of the latter, is so shielded at its opposite sides, considering the lengt-h of the shuttle, that warp-threads bearing on the upper surface of the shuttle are prevented from becoming caught under the flange. The said flange at the forward side of the shuttle projects over the upper end of the vertical slit '7, leading from the delivery-eye 6, so as to cover such end and prevent warp-threads from entering into the same.

In threading the shuttle the yarn is drawn by hand forward from the bobbin 3 over the groove 9, being depressed into the latter and under the flange 131 of the button, then being swung transversely around the button into the vertical slit 7 and down the latter into delivery-eye 6. Outward draft on the yarn, either communicated by hand or occurring after the shuttle has been placed in a loom and picked, will cause the yarn to pass downward through slit 12 into the eye 11 in line with the bobbin and also into the groove 141 of collar 14, or the yarn may be caused by hand to pass downward into and through the slit 12 at the same time that it is being drawn forward into groove 9 and passed under flange 131 of the button. The barrel or body 132 of the button 13 tapers slightly, so as to facilitate the slipping of the yarn downward into the groove 141 of the collar 14. The button is formed witha vertical depending flange 133 extending part way around the same, sufl-A cient space being left between the said flange and the periphery of the collar to permit free entrance of the yarn. The end 134 of the said flange, which is located near the eye 11, slopes or bevels downward in a forward direction to facilitate the descent of the yarn below the flange in the threading operation; but the opposite end of said flange is reversely inclined to form an inclined shoulder 135 and an entrant angle adjacent the same, as indicated in Fig. 6. When the button is in proper position in the threading-chamber, the shoulder 135 is located in advance of the forward side of the shuttle-eye, and thereby is shielded by the said side of the shuttle-eye, so that the yarn in case it should accidentally become lifted upward through slit 7 and drawn reversely around under the flange 131 of the button toward the middle line of the shuttle, as in a flight of the shuttle from right to left in the drawings, cannot become retracted under the point or corner of the said shoulder, and thus is prevented from passing the shoulder. In this case in the next flight of the shuttle from left to right the yarn would find its way back through the slit 7 into the eye G. The shoulder 135 thus constitutes a detent which prevents unthreading.

For the purpose of facilitating the operation of introducing the yarn under the flange 131 the rear portion of the latter is cut away vertically at one side of groove 9 in the top of the shuttle-body on an oblique line, (see Fig. 1,) so as to leave an angular portion 136, and this last is beveled or sharpened, so as to produce a knife-edge-like formation.

Collar 14 is formed separate from button 13 chiefly for convenience in making the parts.

It will be apparent that the construction of the parts may be varied in different respects without necessarily involving any departure from the essential principles of the invention, and I therefore do not limit myself to the precise particulars which are herein shown and described.

The slot 12 enters the'eye or passage 11 at one side thereof, and it extends in the same direction in which the yarn circles around in unwinding from the mass of yarn on the bobbin or spindle in the yarn-containing cavity. Consequently the yarn will tend naturally to pass downward from above from the said slot 12 into the said eye or passage 11, and after it once has entered the said eye it will remain therein. As will be perceived, one side of the slot extends in the direction in which the yarn circles around the eye or passage 11, and consequently protects or shields the said slot, The side at which the slot 12 enters the eye or passage 11 will be determined by whether the yarn is wound to the right ou the bobbins or to the left.

I claim as my invention* 1. A loom-shuttle having the threadingchamber in advance of the yarn-containing cavity thereof, a slitted yarn-passage leading from said cavity to said chamber, the slitted or open delivery eye or educt, the button and grooved collar within said chamber, and the downwardly-extending flange on said button formed with the detent to prevent the yarn from being drawn back from around the button and collar, substantially as described.
